I have a virgin moble lg vm670 smart phone i forgot the screen lock patern and the gmail sing in recovery is not working . can someone help.


Try this:

Use your Google account for unlocking

  1. When you try different patterns and unable to unlock your phone in five attempts. Then a message pop-up and shows two buttons "next" and "try again".
  2. Now click on "next" button and you see two options for unlocking phone. One is answer the security question and the second option is to provide Google account details.
  3. Mostly people don't set a security question. But if you set it then simply answer the question and unlock your device quickly. Otherwise check the Google account option and click "next".
  4. Now provide your Google account username and password attached with your device and click on "sign in".
  5. After that you are directed to choose new pattern and now you can unlock with this pattern.

Unlock pattern without Google account

If you also forget Google account details then what? Here we have solution for this and that is factory reset your android device. Lets talk about how to do it.
  1. Power off your phone.
  2. Now press Volume up, power and home button at the same time and wait until your device starts.
  3. When you see logo screen release the power button and keep pressed the other two buttons.
  4. Now your screen shows android system recovery and there is a list. Use Volume up or down keys to select option from the list. And select factory reset option and then press power button to let the action begin.
  5. Now it asks you for confirmation, select "yes".
  6. After factory reset completes, it again shows you android system recovery screen. Now select reboot option and after restart it will not ask you for pattern.

Reset security code when it's forgotten?


1. *#7780# - Restore factory settings - resets all the settings to the default ( you will not lose any data)
Make sure you back up your data as you will lose all of it when you perform option 2 or 3 on this list.
2. *#7370# - Reformat your phone

3. This you perform as a last resort. Nothing else is working.If the phone is dead proceed with reflash if not, turn off your phone, hold the following buttons while pressing the power button. (the default code is 12345)
re-flash - hold the following buttons *, 3 (number button) and talk/green key. turn on the phone and do not release those buttons until you see the Nokia2.gif boot up screen. once you feel the phone power up you can let go off the power button while still holding all three buttons

If these codes2.gif are not working the only thing for you to do is contact your Nokia Care Center/Service.

Lg vu won't let you dial


Press the unlock button, next to the the camera shutter button, then try again. If that does not work, try turning the phone of for a few minutes and rebooting it. I've had similar problems with my phone as well, but I find rebooting it every 2 days solves this.

Need Master Reset Instructions


The same exact problem is happening with my phone right now. if you need to use it immediately then turn it on and quickly go to the settings menu to turn off auto-lock and try to avoid pressing the side buttons, don't let the phone lock by itself before you get to the settings otherwise you have to take the battery out and try again.

Keys will not work


Sounds like you locked the keypad.

I know you stated all the keys don't work, but let's give this a try.

Press the "unlock" key (the key in the upper left)

Enter your lock code (usually 0000)

Let me know if this helps.
